JOSEPH FRIEDMANN, OF SAN FRANCISCO, CALIFORNIA,

PADLOCK.

SPECIFICATION forming part of Letters Patent No. 389,215, datedSeptember 11, 1888.

Application filed November l, 1887. Serial No. 254,011. (No model.)

To afl?, whom, it may concern:

Be it known that I, J osEPH FRTEDMANN, a citizen of the United States,residing in the city and county of San Francisco and State ofCalifornia, have invented certain new and useful Improvements inPadlocks, of which the following is a speeiication.

My invention relates to improvements in padlocks, which will beunderstood by reference to the accompanying drawings and the lettersreferring thereto.

Figure l is a sectional elevation of the devices embodying` myinvention; Fig. 2, a sectional view cut vertically through the brokenline a a, Fig. 1; and Fig. 3, asectional View cut through the brokenline b b, Fig. I.

A represents the outer shell or case of the lock; B, the link, designedto pass through the staple in locking; C, the lower lock-bolt; D, theupper lock-bolt; E, the lever which connects with the lowerlock-bolt, C,and with the connecting-lever M by means of the key-notch L; F, thepivot upon which the lever E turns; (l, the projection upon the lever Eto force the tumbler H out of the notches I and J; H, the tumbler; I andJ, the tumbler-catch notches; K, the tumbler-spring for returning the turnbler H into the catch-notches I and J and holding the bolt eitherlocked or unlocked.

L represents the key-notch for the levers E and M.

M represents thc lever, which connects with and operates the upper bolt,D, by means ofthe upper arm, N.

N represents the upper arm of the lever M.y

O represents the upper bolt-mortise.

P represents the lower arm of the lever M, which is operated by thenotch L.

Q represents the mort-ise or slot through which the lower arm, G, of thelever E passes.

R represents the key-bit.

S represents the catch projection upon the end of the tumbler H to holdthe same in place either locked or unlocked.

T represents the central pivot, to which the bolts C and l) are hinged.

U represents the pivot of the upper boltconnecting lever.

V represents the tumblervpivot.

XV is the connecti n garni for the upper bolt, D, and X theconnectingarm for the lower bolt, C.

The following is the construction and operation of my improved lock.

I form the lock of such metals as are usually employed in theconstruction of the class of manufacture to which it is related. I hingethe bolts C and D upon the pivot T by means of connectingarms W and X.The lever E connects the key-bit with the bolt C directly through themortise Q. It also connects the same with the bolt D by means of thelever M, keynotch L, and the mortise O. Thekeybit may be fitted with anyrequired variety of gains or slots to operate in connection withcorresponding slots or gains in the key-notch L, none of which areshown, as they may be of any desired form or combination.

I construct the tumbler H with the catch S to hold by means of thenotches I and J. In Fig. l it is shown with the bolts C and D passedthrough the mortise of the link B and locked. To open the same, thekey-bit R is turned down into the keynotch L, and the lever E is forcedback, turning upon thepivot F, and the lower arm, G, impinging upon thetumbler H, forces the same down, withdrawing the catch projection S,and, continuing, strikes the edge of the mortise Q, and moves the boltCout ofthe mortise in the link B. At the same time the lower arm, I), ofthe lever M is operated by the key-notch L and turns upon the pivot U,throwing the upper arm, N, over and withdrawing the bolt D from the linkB and freeing the same, thus unlocking and allowing the link to beopened ont, as in other padlocks.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

Iu a padlock, the combination, with a piv` oted lever, E, having thekey-notch L, and the pivoted lever M, ot' the bolts D and O, pivoted atT, and provided with the mortises O and Q, respectively, for engagementwith the levers, said bolt C having the notches I and J, and the tumblerH, adapted to engage said notches and the link, substantially as and forthe purpose set forth.
